WHIFFLETREE.

SPECIFICATION forming part of Letters Patent No. 679,192, dated July 23, 1901.

Application filed February 18,1901. Serial No. 47,843. (No model.)

To @ZZ whom t may concern:

Be it known that 1, THOMAS P. STALCUP, a citizen of the United States, residing at Butte, county of Boyd, State of Nebraska, have invented certain new and useful Improvements in Vhiflletrees, of which the following is a specication.

This invention relates to whiiiletrees.

One object of the present invention is the provision of a Whiffletree comprising a doubletree of improved construction and arrangement and singletrees connected to the improved doubletree in a novel manner, whereby great freedom of movement is obtained in the doubletree and singletrees and the strain is more evenly apportioned between the tongue, the doubletree, and the singletrees, a further object being the provision of a Whiffletree of strong and durable construction and of comparatively small cost.

Having the foregoing and other objects in View, the invention consists of a Whifiietree of improved and novel construction comprising` certain features and adaptations of parts more fully set forth hereinafter and recited in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of the invention; Fig. 2, a detail section taken longitudinally through the tongue, and Fig. 3 an enlarged detail of the construction at the ends of the doubletree.

The tongue is shown at 1. The doubletree is composed of two members 2 and 3, located on top 'of the tongue and pivoted thereto on bolts 4 and 5, which pass through the tongue and through a yoke 6, having its ends secured to the tongue at 7 and forming a brace and guide for the members of the doubletree. The bolts 4 and 5 are located suiiiciently far apart to give the doubletree members 2 and 3 complete freedom to move without touching each other, said doubletree members being thus disposed in spaced or separated arrangement to each other. The ends of the doubletree members 2 and 3 are connected by upper and lower plates or links 8 and 9, bolts 10 and 11 passing through the ends of these links and the ends of the members 2 and 3. On the plates or links 8 are located yokes or clips 12, in which the singletrees 13 are located and pivoted on bolts 14, which pass through the clips 12 and plates or links The singletrees are thus free to 8 and 9.

move on their pivotal connections independently of the position of the doubletree members 2 and 3, While the links 8 and 9 maintain the ends of the members 2 and 3 separated, so that they are in parallel relation to each other, and the bolts 14 not only provide a pivotal connection for the singletrees, but also strengthen the plates S and 9.

It will be seen that the strain on the doubletree is divided between the pivotal counections 4; and 5, and also the plates B and 9 insure the division of the strain between the ends of the two doubletree members. The strain on the singletrees is taken at the point of their pivotal connections, and as these pivotal connections are located between the ends of the doubletree the strain on the ends of the members 2 and 3 is thus equalized. My invention provides a whiffletree construction which is simple, strong, durable, and capable of perfect freedom of movement in all of its parts.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

1. In a whiffletree, the combination with a doubletree composed of independent, separated, members, pivoted one in front of the other, of links pivotally connected to the members of the doubletree and keeping said members separated, a yoke or clip connected to said plates, and singletrees located under the yokes and on the plates and pivotally connected to said yokes and plates.

2. In a Whiftletree, the combination. with a tongue, of a yoke secured thereto, a doubletree composed of independent members located between the yoke and the tongue, one in 'front of the other, and independent connections pivoting said members to the yoke and tongue, links at the ends of the doubletree members, above and below the same, yokes or clips on the upper links, pivotal connections securing the ends of the clips and links to the ends of the doubletree members, and singletrees pivotally mounted between the clips and the plates.

In testimony whereof I hereunto affix my signature in presence of two Witnesses.

THOMAS P. STALCUP'.
